Technical data and characteristics
4.1 Mode of operation and characteristics
Power rating data for duty types S1 and S6
All power rating data of induction motors refer to continuous operation and the appropriate
duty type S1.
However, for many applications, duty type S1 does not apply, if e.g. the load varies as a
function of time. For this particular case, an equivalent sequence can be specified which
represents, as a minimum, the same load for the motor.
For shorter accelerating times, torque surges or drives which have to handle overload
conditions, short-time or peak currents are available in a 60 second cycle. The magnitude
and precise engineering of these currents are described in the documentation for the
relevant converter power units or Motor Modules.
The characteristics for continuous duty S1 and intermittent operation S6-60 %, S6-40 % and
S6-25 % describe the permissible power values for an ambient temperature of up to 40 °C. A
winding temperature rise of approx. 105 K can occur.

appropriately designing the control or by activating the speed monitoring in the drive.
Output voltages
The converter output voltages differ according to the converter type and supply voltage.
